The appellant or appellants, applicant or applicants, relator or relators, as the case may be, shall have the right to open and close the argument. When there are two or more appellants, applicants, or relators in the same case, the court shall decide, when the case is called for argument, who shall open and who shall close the argument, unless the parties agree upon the one who shall open and upon the one who shall close the argument.
